The Flare Cue indicates a flight path to touch down at approximately minus one degree. The Flare
Cue is displayed vertically in relation to the horizon line at a fixed pitch attitude and laterally in
relation to the flight path vector.
The flare cue is displayed when the FD is in Approach mode, the radio altitude is lower than 50
feet, and the main wheels are weight-off-wheel.
Decision Height (DH) Readout
The Decision Height (DH) indication is located at the left of the BARO set readout. The DH readout
is displayed in 10 foot increments and labeled RAD when the selected DH is valid and greater than
20 feet.

Minimum Alert Indication
When the minimum alert indication is armed, a window is displayed to the right of the radio altitude
readout. When the DH or the MDA is reached, a MIN annunciation appears inside the window.
The MIN annunciation is removed when the Radio Altitude readout is removed as the airplane
transition to weight on wheel condition.
The minimum alert indication cannot be displayed when:
• The minimum alert is not set ON, or
• The selected DH/MDA is invalid, or
• A BARO altitude miscompare exists for DH/MDA annunciation.

AP Status Annunciation
The status of the Autopilot is displayed above the altimeter tape. When the autopilot is engaged,
AP1 or AP2 annunciation is displayed.
This annunciation blinks for a 10−second time period when the AP source is changed.
In the case of an autopilot abnormality, the annunciation blinks until the fault is rectified, the pilot
manually disengages the autopilot or the other autopilot is selected.
In case of an uncommanded autopilot disengagement, the annunciation is boxed and blinks until
the pilot acknowledges the fault by pressing the Autopilot Disengage switch.
FCS Couple Arrow
The Fligth Control System (FCS) Couple Arrow is displayed below the Autopilot Status
Annunciation to indicate which FCS is active. Only 3 possibility exists:
→ FCS coupled to the right side
← FCS coupled to the left side
↔ Both FCS are active.

FCS Couple Arrow (Cont’d)
The double arrow is only displayed during ILS approaches. The FCS Couple Arrow blinks for 5
seconds after the Couple Arrow has been altered in direction. This can be selected from the flight
guidance panel. A ghosted arrow indicates a failed FCS condition or an AFCS fail condition.

AP/FD Mode Guidance Cue
The guidance cue is a circle that is displayed in reference to the FPV. Tracking of the FD results
in a concentric display of the guidance cue and the FPV.
The guidance cue is displayed in the T/O mode one second after nose wheel lift off. The guidance
cue is removed during excessive airplane attitude, TCAS resolution advisories, loss of FD modes,
manual disengagement of the FD and at an approach height of 50 feet.
In the above example, the pilot or the autopilot has to roll the airplane to the right and pitch it down
in order to track the guidance cue.
Autothrottle Annunciation
The autothrottle mode is shown above the airspeed tape. The following modes can be displayed:
LIM for limiting speed condition
SPD for control of airspeed
GA for go-around mode
RETARD for landing retard mode
